Item Description:

The HRT-556™ features the patent pending DUAL-LOK™ mounting system, an accurate, robust, reliable, and wear free system with robust muzzle device support.  The suppressor itself was designed to have minimal flash signature, despite its size, minimal weight, minimal POI shift, minimal gas blow back, maximum strength, durability, and sound performance.  This was a tough list of performance attributes to tackle, but Griffin succeeded by bringing unbeatable sound suppression and flash reduction to this compact suppressor.
